Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∣ Angles around a point.
(x+y)+(w+z)=360
(x+y)+(x+y)=360
∣ Given x+y=w+z
2(x+y)=360
(x+y)=180
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
those are two different ways you can split the shape
